I'm sorry, I will try to stop after this, but I've been teaching a long time. I've got a pretty good handle on discipline, but to talk about "better control in a classroom" especially when you're talking about very young children (ex Kindergarten/1st grade), some of those children have multiple daily meltdowns in the best of times. I teach 5th grade, and I love it. They're my people and I want to be with them. But even at 10/11 years of age, many children have impulse control issues. They're KIDS. To think of them as little soldiers, sitting quietly behind their plexiglass divider is ludicrous. And I'll be surprised if my district (or "most" districts) have plexiglass dividers around every desk. My classroom won't fit 20 children with 6 feet of distancing. I don't have desks in my room, I have tables because we like the sense of community. It's possible that each child could have their own trapezoid table. I have a dozen of them, but from what I understand, most of our classrooms will only be able to 8 or 9 students w/ appropriate distancing. The guidelines that schools are trying to deal with make no sense to anyone with an understanding of what an actual classroom with real live students involves.
